TPS566231RQFR Description

Short technical summary and product information.

The TPS566231RQFR from Texas Instruments is a high-performance, 6-A synchronous step-down voltage regulator. It operates with an input voltage range of 3 V to 18 V and can provide an output voltage as low as 0.6 V up to 7 V.

 

This regulator utilizes the D-CAP3 control mode, which offers fast transient response and internal compensation, simplifying design efforts. It features a fixed switching frequency of 600 kHz and a maximum duty cycle of 98%. The device includes integrated power MOSFETs with low RDS(on) and supports features like light load efficiency, over-current protection, and power good indication.

 

The TPS566231RQFR is housed in a compact 9-VQFN-HR package measuring 1.5 mm x 2.0 mm, making it suitable for space-constrained applications. Its surface mount type facilitates easy integration into PCB designs. The operating temperature range is -40°C to 125°C (TJ).

 

This component is configured for rugged applications and offers non-latched protections for OC, OV, UV, and OT. It also includes a built-in output discharge function for added design flexibility.
